Published annually, the Physicians Desk Reference is a guide to prescription drugs available in the United States, according to MedicineNet. The PDR is used to look up information about drugs by product, nontrademark common drug name, manufacturer or category such as antihistamines.
A thick volume, the PDR is the most commonly used drug reference, according to MedicineNet. Pharmaceutical companies pay to get their drugs listed, meaning that many generic medicines are not included within the reference. The information provided in the book is the same as in the package insert that is included in the package when a patient picks up a prescription at the pharmacy.
Because pharmaceutical labeling information changes, an up-to-date copy of the book is available online, according to PDRBooks.com. Also on the site, individuals can obtain free access to Web and PDF e-book versions of the current manual and to iPhone and Android mobile applications.
Alternatively, individuals can search online free of charge to obtain the same package insert information as is found in the 2015 edition of the book, according to PDR.net. The pharmaceutical drug descriptions include information on topics such as how the drug is administered and supplied, dosage, warnings and cautions, adverse reactions, and drug interactions.
